Figure 2.
Numerical simulations demonstrate the condition for evolutionary invasion of queen control ((a), Condition (1)) and the condition for queen control to be evolutionarily stable, when fixed, against invasion by noncontrolling queens ((b), Condition (2)). For these plots, we consider a dominant queen‐control allele with singly mated queens (n = 1), and we set p = .5, p′ = 1, and r = 1. (The initial conditions are (a) X AA, 0 = 1 − 10−3 and X AA, 1 = 10−3 for each of the four curves, and (b) X aa, 1 = 1 − 10−3 and X aa, 0 = 10−3 for each of the four curves.)
